IVIOLDERS SLICK.

Application tiled June17,1903. Serial No. 161,917. (No model.)

a citizen of the United States, residing at 783 Mission street, SanFrancisco, in the county of San Francisco and State of California, haveinvented certain new and useful Improvements in Molders Slicks; and I dohereby de- @lare the following to be a full, clear, and exact descripiion of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention is au improvement over the devices shown in myapplication filed July 23, i902, Serial No. llt,92, and in addition topossessing all the advantageous features of said former application itssimplicity and security of construction are brought to a higher degreeof perfection, .Y

As in my formerinveul'iomvarious sizes and forms of 'tools can beattached to the handle, or the latter can he adjusted in length to suitany particular purpose. The handles are made double-ended to accommodatetools at both ends or permit of several lengths of handles beingconnected together. I have constructed the handle and connecting meansfree from any surfaceirregularity and in that way lessen the liabilityof injuring the mold`as the molder is slicking it.

The device is clearly illustrated in the accompanying drawings,in which-Figure l is a perspective View of a heartslick and a spoon slickconnected together by means of my detachable handle. Fig. 2 is a sectionshowing the manner of connecting the handle with the tool. Fig. 3 isasection taken at right angles to that shown in Fig. 2. Fig. 4 is aperspective view of several joints of handle and the coupling employedto unite them. Fig. 5 is a perspective View of the tool-shank, therelative position of the handle being shown by means of dotted lines.Fig. 6 is a perspective View of an egg-slick,

` showing the ordinary handle removed and a webbed handle set in placefor shallow molds.

Referring now to the above views by'reference characters, 1 and 2 areordinarily: formed heart and spoon slicks, respectively. Extendingoutward at an angle with the body of the slick is the integrally-formedstem 3, which is adapted to enter the tubular handle 4.

This stem 3 is formed at its outer end with two legs o. and b, whichgradually diverge, leaving an interposed tapered slot c. At the base ofthis stem 3 are the diametrically opposite tapered vlugs 5, Whilecorresponding with these lugs and adapted to receive them. are the slots6, cut in the extremities of the handle. .I ust above the slots 6 andpassing transversely throughthe tubular handle are the pins 7.

Now it will be readily seen that as the stem 3 is forced into the open'end ot' the tubular handle 4 the legs a and b will straddle pin 7, andas the stem is forced farther home the relatively narrow portion of theslot c will bind on the pin and hold it fast. To permit of a slightspring of the legs aand b, I have out away the outer surfaces, as shownat d. Simultaneous with the above operation the lugs 5 will enter slots6 and tend to spread the opposite walls thereof, thereby adding furthersecurity-against accidental disengaging of the slick from the handles.

In preparing deep and complicated molds the melder often has occasion toemploy a comparatively long handle, and in order to fulfil thisrequirement I have provided the coupling 8, (shown in Fig. 4,) which isformed with double-ended stems 3, which unite eX- tra lengths of handles4 and 4". yThese stems and handles and manner of connecting same areidentical with the slick stems and handles above described.

This invention is of great importance to foundry-melders, for by its usea larger variety of tools will constitute the molders kit, as theexpense of purchasing a handle for each tool can be diverted toaccumulate additional tools.

The practical value of the invention has been completely demonstrated bythe inventor, who has had forty years experience as a skilled melder.

' In Fig. 5 the lug 5 takes the place of lugs 5, and in that case theend of` the handle is out away correspondingly.

What I claim,v and desire to secu re by Letters Patent, is Y 1. #Amolders'tool formed with a projecting stem, a handle adapted to beremovably connected to said stem and a spreading yielding fork on said.stem, said handle being provided together by means of a suitableremovable Io with a transverse pin to engage said fork and coupling forthe purpose set forth. force the legs thereof apart for the purpose Intestimony whereof I afx my signature set forth. in presence of twoWitnesses. 5 2.
